The dimethylbis(α-lithiobenzyl)silanes and -germanes were prepared by the reaction of dimethylbis(α-thiophenylbenzyl)silane or -germane with lithium dispersion and their reactions with Me3M′Cl (M = Ge, Sn) investigated. The lithium compounds proved to be useful in the synthesis of 2,4-diphenyl-substituted 1,3-disila-, 1,3-digerma- and 1-germa-3-silacyclobutanes.
